§8378. Steam Supply and Hose.

(a) Steam supply system.

(1) Prior to supplying a vessel with steam from a source outside the vessel, the employer shall ascertain from responsible vessel's representatives having knowledge of the condition of the plant, the safe working pressure of the vessel's steam system.

(2) The employer shall install a pressure gauge and a relief valve of proper size and capacity at the point where the temporary steam hose joins the vessel's steam piping system or systems. The relief valve shall be set and capable of relieving at a pressure not exceeding the safe working pressure of the vessel's system in its present condition, and there shall be no means of isolating the relief valve from the system which it protects.

(3) The pressure gauge and relief valve shall be located so as to be visible and readily accessible.

(4) Each relief valve shall be positioned so it is not likely to cause injury if steam is released.

(b) Steam hoses. The employer shall ensure that each steam hose meets the following requirements:

(1) The steam hose and its fittings are used in accordance with manufacturer's specifications;

(2) Steam hose and fittings shall have a factor of safety of at least five.

(3) Steam hose shall not be bent at a radius of less than 5 feet which would result in kinking.

(4) Each steam hose is hung tightly with short bights that prevent chafing and to reduce tension on the hose and its fittings;

(5) Each steam hose is protected from damage; and

(6) Each steam hose or temporary steam piping, including metal fittings and couplings, that pass through a walking or working area is shielded to protect employees from contact.
